Microsoft Windows® PowerShell is a new command-line shell and scripting language designed for system administration and automation. Built on the .NET Framework, Windows PowerShell enables IT professionals and developers control and automate the administration of Windows and applications.

• More than 130 command-line tools (called "cmdlets") for performing common system administration tasks, such as managing services, processes, event logs, certificates, the registry, and using Windows Management Instrumentation (WMI).

• Command-line tools are designed to be easy to learn and easy to use with standard naming conventions and common parameters, and simple tools for sorting, filtering, and formatting data and objects.
